Hawassa University is conducting land use analysis to identify populations at risk from various disasters in the Rift Valley. The OSM data will be the base map this analysis is based on.
Tracing the buildings in this area can be challenging, please take your time to ensure accurate square buildings, and buildings that do not overlap.

When saving your work, please leave the default comment but add what you actually mapped, for example "added buildings and a residential road".

Buildings

Please accurately outline all the buildings you can find. The outline should be for the full size of the building even if it is partly covered by trees in the imagery.

After drawing the outline, use the 's' key in the iD web editor (the 'q' key in JOSM) to "square" the corners.

Many buildings are very close, but do not actually touch each other, try to map them close to each other without letting them connect or share nodes with each other, roads or residential area outlines. In the iD web editor, holding down the "alt" key will keep nodes of "snapping" to each other and accidentally connecting.

In the iD web editor, the first time you map a building you will use the "Building Features" category and then at the top of the list select "Building" again, this is the most generic building tag we can use as we almost never can tell the more specific use of any building from imagery alone.

If you have personal knowledge of a building, please add that information to the building, like the name or type of building (hospital, school, gas station, etc)

Roads and Paths

Please map major paths as completely as possible by connecting them to the main road networks where ever possible.

You will most often use the following "Road Features" and "Path Features" (iD Web Editor):

Unmaintained Track Road - This is for roads that only lead to farm fields or forests. They do not connect settlements or residential areas.

Path - This is for small paths that are usually used by people on foot or 2 wheeled vehicles. They may or may not connect settlements or lead to farm fields. Only map the major paths that connect to settlements or other roads.
